BACKGROUND OF THE INVENTION
The present invention relates to a package packaging method and apparatus for winding and packaging a package around a package carried in by a carry-in conveyor in a spiral shape in a vertical direction and a horizontal direction.
[0002]
[Prior art]
As a conventional load body packaging method and apparatus of this kind is known that shown in Japanese or Japanese Table flat 8-508223 Patent Publication No. Sho 59-46845.
[0003]
In the former, the load can be placed on a conveyor whose upper surface and lower surface move in the same direction and at the same speed, and the entire conveyor can be extended around the load moving by the conveyor. A web of material is wound and moved to a position beyond the downstream end of the conveyor so that the web contracts at a position away from the conveyor and is wound only on the load.
[0004]
In the latter case, as an embodiment, on the first table, a web is wound around the load on the table in a direction perpendicular to the horizontal direction, and the load is then moved to the second table. After moving on the table, the second table is wound around the load on the second table by rotating the second table in the horizontal direction around the vertical rotation axis. The web is further wound in a direction perpendicular to the web.
[0005]
As a second embodiment of the invention, the packaging means is rotated in a horizontal plane, and the load is rotated around the horizontal axis, that is, in the vertical plane, and the packaging means is rotated. By rotating the load body, the load body is web-wrapped from both the vertical direction and the horizontal direction.
[0006]
[Problems to be solved by the invention]
The former of the prior art described above is unsuitable as a packaging means for a cubic load because the web can be wound only around the horizontal axis of the load.
[0007]
On the other hand, in the latter of the prior art, the web can be wound around both the horizontal axis and the vertical axis of the load body. In the embodiment, the web roll is tilted by 90 ° during the winding process to the load body in order to wind the web in different directions on the load body on the first and second tables. In addition, the second table has to be rotated, and the double winding operation is troublesome, and the mechanism for implementing this is complicated.
[0008]
In the second embodiment, the web can be wound twice around both the vertical and horizontal axes while the load remains in the same position. Since both a mechanism for winding the web around the horizontal axis and a mechanism for winding the web around the vertical axis are required, there is a problem that the configuration becomes large and complicated.
[0009]
The present invention has been made in view of the above, and using a general load packaging apparatus for winding a film around a horizontal axis, the axis around the horizontal axis of the load and both the horizontal axis and the vertical axis.

In a package packaging method in which a film fed out from a film roll is spirally wound,
A film is squeezed into a string from at least one film roll that wraps around the moving load, and the film is wound from another film roll as a band,
While the load body moved in one direction in the direction of the rotation axis of the film supply machine, a string-like film and a belt-like film were overlapped on this load body and wound in a spiral shape .
[0011]
Then, after the film is wound around the load by this load packing method, the film is moved to a position where it is removed from the position where the film is wound by the film feeder, and at this position, the load is moved either horizontally or vertically. Rotate 90 ° to either side, then move the load in the reverse direction, and follow the movement of the load in the reverse direction to squeeze the film from at least one rotating film roll into a string, Wrap the film in the form of a strip from the film roll,
While it is moving in the opposite direction of the load body, and to be wound around et linearly superposed film and strip of film string-like to the load body.
[0012]
And the package packaging apparatus according to the present invention for carrying out the above method, the film feeder spirals around the horizontal axis, so that the film is spiraled to the package that moves by the conveyor mechanism located inside it. In the package packaging device that is wound in a shape ,
Multiple film feeders are used, and at least one film feeder is provided with a squeezing roller that narrows the width of the film at the film feed port, so that a string-like film can be fed, and a strip-like film is fed from other film feeders. Enable
While the load body moves in one direction, a string-like film and a band-like film are overlapped and wound around the load body .
[0013]
In the package packaging apparatus, the conveyor mechanism can be traveled in both directions, and the conveyor mechanism is disposed on one side of the conveyor mechanism and at a position outside the position where the film is wound around the package by the film feeder. The load body that has been moved by the mechanism is rotated by 90 ° in either the horizontal direction or the vertical direction, and is provided with table means for moving to the conveyor mechanism again .
[0014]
[Operation]
While the load moves in one direction inside the circulating film supply machine , a string-like film and a belt-like film are overlapped on the load and wound in a spiral shape.
[0015]
Then, after the film is wound as described above, the load is rotated by 90 ° at a position outside the position where the film is wound on the load, and then again moves in the reverse direction to the inside of the film feeder. In the meantime, in the direction perpendicular to the winding direction of the film wound as described above, the string-like film and the belt-like film are overlapped and wound in a spiral shape. A string-like film and a belt-like film are overlapped and wound on all the surfaces.

The operation in the first embodiment will be described below.
The load 7 is carried onto the conveyor mechanism 6 of the ring packaging apparatus 1 by a conveyance conveyor (not shown). The load 7 is conveyed downstream by the conveyor mechanism 6. At this time, the cutting device 10 is moved to a position where it does not interfere with the circulating film 9. In this state, the ring packaging apparatus 1 is operated to wind the film 9 around the load body 7 together with the conveyor mechanism 6. The film 9 is spirally wound around the film 9 while being stretched as the load 7 moves. The film 9 wound around the lower portion of the conveyor mechanism 6 moves downstream at the same speed as the load 6 according to the movement of the film belts 6b, 6b.
